What was your worst ride ever?

I'll go
>in the middle of a 50 day tour
>middle of nowhere Montana, about to cross continental divide
>early start, stop for breakfast 30 miles in
>check route
>Adventure cycling diverts us 50 miles north
>decide to take a short cut, which should end up being a 90 mile day
>locals say it's not too bad
>steady incline to divide, as soon as we hit the top we get a headwind
>have to pedal downhill, day starts to heat up
> hit mile 60, and we expected a gas station to fill up
> it's closed
> mile 65 the hills start
>3 600 foot climbs each about 9%
> run out of water after the second
>still 15 miles to go and Garmin says 96℉
>skipped lunch to beat heat, so I'm starving at this point
> finally see sign that the 'town' is 2 miles away as it is getting dark
>group member gets a flat
> change it
>the valve is broken
>change it again

Limp into town and the restaurant is out of business. We camp behind a closed gas station and eat trailmix with hose tasting water for dinner. No shower, no bathroom, just highway sounds all night

Pic unrelated but I got some mini gourds at a farm stand on my ride today
